Boxing Scene reported that Caribe Promotions CEO Boris Arencibia informed them that Rigondeaux already signed the contract to face Donaire in a title-unification bout on April 13 either in California or New York.

Arencibia said that final contract of the details will be announced soon after Caribe Promotions and Top Rank Promotions settle their dispute, which is related to the Cuban champion’s promotional contract.

Arencibia was quoted by Boxing Scene as saying: “We had to negotiate with Top Rank from another angle. For the time being we have come to a partial agreement on this fight after several hours in the office of our lawyer. We could reach a full agreement, but it won’t be until Saturday when we are able to confirm that the fight is a fact.”

Despite the distractions caused by the promotional contract disputes, Arencibia is confident that it will not affect the performance of the two-time Olympic gold medalist.

The Caribe Promotions CEO confidently said that Rigondeaux will go for a knockout win against the consensus 2012 Fighter of the Year, saying that Donaire has never faced a fighter like the undefeated Cuban.

“Rigondeaux has to be fully prepared and focused for this fight. The distractions that were generated by the negotiations to make the fight, they were overcome to a great extent, and we are sure that without this extra pressure and the stress that the legal dispute produced, Rigondeaux will return to training with more motivation because these are the kind of fights which made him decide to enter prizefighting.”

But while Caribe Promotions claimed that a partial agreement has been reached, the Donaire vs Rigondeaux bout will remain in doubt and it could pave way to another fight for Donaire – against his former prey Vic Darchinyan.

Reports confirmed that Darchinyan, who absorbed a fifth-round knockout loss against Donaire in 2007, remains an option for Donaire, considering the fact that Top Rank boss Bob Arum’s previous hints about the better marketability of a Donaire vs Darchinyan rematch.
